The example deployment manifests provide an example (commented out) for providing Custom configuration with an additional ConfigMap, mounted into the custom.d directory. This directory must be available inside the NFD worker container, so Volumes and VolumeMounts must be used for mounting e.g. This makes more dynamic and flexible configuration easier.
Additional configuration directoryĪdditionally to the rules defined in the nfd-worker configuration file, the Custom feature can read more configuration files located in the /etc/kubernetes/node-feature-discovery/custom.d/ directory. To aid in making Custom Features clearer, we define a general and a per rule nomenclature, keeping things as consistent as possible.

See configuration for instructions and examples how to set-up and manage the worker configuration. The rules are specified in the nfd-worker configuration file. A rule is provided input witch affects its process of matching for a defined feature. The Custom feature source allows the user to define features based on a mix of predefined rules.

By default, the following CPUID flags have been blacklisted: BMI1, BMI2, CLMUL, CMOV, CX16, ERMS, F16C, HTT, LZCNT, MMX, MMXEXT, NX, POPCNT, RDRAND, RDSEED, RDTSCP, SGX, SSE, SSE2, SSE3, SSE4.1, SSE4.2 and SSSE3. For examples and more information about configurability, see configuration. attributeWhitelist has priority over attributeBlacklist. With blacklist, only blacklisted attributes are filtered out. If whitelist is specified, only whitelisted attributes will be published. The (sub-)set of CPUID attributes to publish is configurable via the attributeBlacklist and attributeWhitelist cpuid options of the cpu source.

The cpu feature source supports the following labels: Feature name This includes any restrictions placed on the consecutive run, such as restricting discovered features with the -label-whitelist option. If features are not discovered on a consecutive run, the corresponding label will be removed.
